[texdoc] Documentation for newtx

[Bruno Voisin]

Using MacTeX 2020: "texdoc newtx" opens

	/usr/local/texlive/2020/texmf-dist/doc/fonts/newtx/newtxdoc.pdf

as it should, but "texdoc newtxtext" and "texdoc newtxmath" open

	/usr/local/texlive/2020/texmf-dist/doc/fonts/newtx/implementation.pdf

instead.

I noticed this when realizing my favorite journal style had switched a few days ago to using newtxtext and newtxmath, and resorting to texdoc to figure out what this was about.

Some details below.
